Mad Matter is an addictive, super-soft modeling compound that shapes easily. Press it, mold it, knead it, stretch it, squeeze it, paint it, sculpt it, float it, sink it, or just pull it slow and watch it flow! And clean up is a breeze, since it sticks to itself and not to you. Mad Matter is gluten, casein and wheat-free, and available in multiple colors that can be mixed together, too! For Ages 3 and up.
